Embodiment 1

[0031] Embodiment 1: Production of antistatic, weather-resistant PVC matte sheet for lighting

[0032] 1. Preparation

[0033] Weigh 700kg of polyvinyl chloride, 30kg of titanium dioxide, 100kg of nano-calcium carbonate, 50kg of matting agent, 20kg of antistatic agent, 6kg of anti-ultraviolet absorbing agent, 64kg of reinforcing agent, 15kg of heat stabilizer and 15kg of lubricant.

[0034] 2. Processing technology:

[0035] 1. Stir the molten material at high speed. Put the above-mentioned raw materials into the high-speed mixer according to the proportion, fully stir and mix evenly, and stir until the material temperature is 105-115°C;

[0036] 2. Stir and cool the material at a low speed. Discharge the high-speed stirred material to a low-speed cooling mixer for cooling and stirring, so that the temperature of the material drops to 40-45°C;

[0037] 3. Plasticization of extruder: Evenly input the cooled material into planetary extruder for plasticization, and the temperat...

Embodiment 2

[0042] The difference between embodiment 2 and embodiment 1 is only that the proportioning of each raw material is different: 750kg of polyvinyl chloride, 20kg of titanium dioxide, 100kg of nano-calcium carbonate, 20kg of matting agent, 26kg of antistatic agent, 4kg of anti-ultraviolet absorber, enhanced Agent 60kg, heat stabilizer 10kg and lubricant 10kg.

[0043] All the other are with embodiment 1.

Embodiment 3

[0045] The difference between embodiment 3 and embodiment 1 is only that the proportioning of each raw material is different: 700kg of polyvinyl chloride, 20kg of titanium dioxide, 100kg of nano-calcium carbonate, 25kg of matting agent, 50kg of antistatic agent, 5kg of anti-ultraviolet absorber, enhanced Agent 80kg, heat stabilizer 10kg and lubricant 10kg.

Description

Technical field: [0001] The invention relates to a PVC hard sheet. In particular, it relates to an antistatic and weather-resistant PVC matte sheet for lighting decoration and a preparation method thereof. Background technique: [0002] PVC hard sheet is a material for making lighting. At present, various lampshade manufacturers at home and abroad use PVC hard sheets. The sheet is a two-sided gloss board, the surface of the material is poor in printability, the printed ink is easy to fall off, and there are disadvantages in weather resistance, antistatic property, rigidity and the like. Because the PVC sheet is exposed to light for a long time, there will be variation or aging of the sheet material, and the color of the material will change color. The above problems are mainly caused by ultraviolet rays in the light. The general antistatic agents are penetrating type, which are easy to precipitate on the surface of the product, thus affecting the printing performance of ...
